摘　　要：针对现有传感器网络节点低功耗设计很难从系统角度提供整体设计方案的问题,提出节点在软硬件方面的设计策略。通过对集成电路和外围电路的研究,提出了可供广泛使用的低功耗布局和设计思想,采用外设按键发送节点身份信息的方法解决节点和位置点间对应关系的问题。在此基础上,通过对通讯模式、发送周期及次数和睡眠模式等软件设计方面的研究,提出适用于不同工程需求的软件低功耗运行策略。最后,设计并实现安全带插拔状态监控的低功耗系统,对此系统进行联调实验,提出系统使用节点的耗电模型并预测其使用时限,最长时限约为4.81年,满足系统对有源RFID节点一次满电的寿命要求。To solve the problem that it is difficult to provide the system power-saving design scheme for sensor network nodes,the node hardware and software design strategies are proposed.Based on the research of integrated circuit and peripheral circuit,puting forward a power-saving layout and design idea which can be widely used.On this basis,the software power-saving strategies,which can be suitable for different engineering requirements,are proposed through the research of communication mode,transmission cycle,times and sleep mode.Finally,safety belt monitoring powersaving system is designed and realized.The combination experiment has been conducted.The power consumption model of this system is established and the node service life is predicted.The maximum life is about 4.81years,which can meet the system application requirements.
